The Brynderwyn Range or Brynderwyn Hills is a ridge extending east–west across the Northland Peninsula in northern New Zealand some 60 kilometres south of Whangārei, from the southern end of Bream Bay in the east to the Otamatea River (an arm of the Kaipara Harbour) in the west.

Though not of great height (reaching only some 450 metres) it is a notable feature of the Northland Region's geography, not least because it is traversed by State Highway 1, which is forced to follow a tortuous route for some distance as it descends to the south.

There are different walks of up to 10 km giving views of the Whangārei Heads, Bream Bay and out to sea.

[5] On 7 February 1963, a bus crashed after losing control of its brakes while nearing the top of the southern descent, killing 15 of the 35 people on board.

[6] In July 2014 the presumed remains of a 20-year missing Northland man were found there by forestry workers on a steep hillside.
